Specification of Letters Patent. Appiicationled June 14, 1910` SerialNo. 566,77-.

To all whom 'it may concern:

Beit Aknown' that we, PERRY FRAIZER and ENooii A. NATION, citizens ofthe United States, residing'at Newcastle, in the county vented a new anduseful 4Heater, of which the .following is a specification. The objectof our present invention is to combustion wherein is supplied by anoillamp.

. A-heater embodying ourfsaid invention will be first fully described,and the novel@ features thereof then pointed out in the :Referring tothe accompanying drawings,

The action of the heat upon the water contained within theboiler-clmmhcr 24. .has

the e'lect of'geuerating steam, which passes up through openings atllfin the overhead wall or ceiling 'of said.boiler-chamlufr, and entersan annular chamber 32 ha ving radial hollow' ribs which have the effectof greatly .increasing its external superlicial 'f The formA of thissteam chamber isarca.

best shown in Fig. (3, the boiler-chamber" is of an oblong. charactcr,and is rentrally positioned between two lue openings .4l and 42which'occupy the remainder of the cross-sectionalarea of 'thestrliclure. These openings unite in the annular jlue elisituated betweena water taule-28 and the steam chamber 82, and the products ofcombustion from thelamp Ypassup #fuif-)ugh said openings and liuc, andescape. through the top ist of the heater. The necessary air to produceeffective combustion is supplied through a series of fine perform-ionsin the wall of the base surrounding'the burner of the lamp:

Our improved heat-er -is preferably made in two parts. and the packingor gasket il is interposed between them, andthe two parts are securedtogether by screws o r bolts When necessary for mrposes of clean ing,repair or otherwise, t. iese' two parts can the 'taule as fastas it isconverted into Steaua, 'The heater isthus adapted 4tofoperatefor aconsiderable period without replenishment. Tlus heater, as a whole, issmiplyjand easily` constructed, and produces a' very.

large amount 'of heat in proportion to the fue] consumed. It is'alsoconvenient and' port-able. 'It is customarily provided with y ahandle 61 by whichit may be carried. from place to place. 7

Having thus fully described our said invention, What .we claim as new,and desire to secure by Letters Patent, istei l.l The combination, 1n aheater, of a Water a steam chamber Surrounding I said Water Supply tank,a boiler chamber ar-r-v supply tank,

ranged below the Water supply tank and communicating ,withthe Water,supply tank and steam chamber, ineansi'or controlling the How of waterfrom'the Supply tank to the boiler, a combustion chamber arranged belowthe boiler and provided with an out` let passage for theproducts ofcombustion,

said outlet passage leading freinl the coinbustionicharnber between theWater supply tank and the Steam chamber, and a burner arranged in thecombustion chamber.

2. The combination, ina heater 'of a coinbustion chamber, a burnercontained therein, a boiler. chamber arranged above said conibustionchamber, a Water -supply tank arranged above said boiler chamber, aconduit leading from said 'Water supply tank to said boiler" chamber, avalve Within said boiler chamber controlling 'the outlet from trollingsaid valve, and an annular Steam chamber, having radial hollow ribs, ar-

rangedabove and in communication With said boiler chamber and spacedfrom the -water supply tank, the combustion chamber having anoutletpassage lying between the Water-snpplywtank and steamv chamber.
